I've had the bike since early December, and I'm on tube number 10. That's a bad number. The flats always seem to happen on the trail, miles from nowhere, at night, and when it's cold, windy, raining, or all of the above.
The tube I yanked out was an easy boo-boo to spot. 18/23c road tubes don't last long when ridden hard off road in 34c cyclocross tyres. So the first step was to dig the appropriately sized tube from my stash.
I was pretty sure that what I was about to put in there was dfferent than what I had used previously because I didn't recognize the threadness chrome valve stems. Interesting.
I give up. I grabbed a DIFFERENT BRAND of tube, installed it and cranked 'er up to 80psi. No it's a waiting game. Will it be flat by morning?
